Have you looked at DP (Digitalpoint) threads lately? If so, you may have gotten confused about why so many avatars all look the same. Why are there nearly 250,000 posts showing SiteSift avatars? Well, that's because Stuart McHenry had the ingenious idea of using avatars as an advertising medium. He rented the avatars of some members, and other members voluntarily changed the avatars to the SiteSift avatar. Stuart explains avatar advertising here and is interviewed about it here. I love a good idea when I see one!
